change the name for the flag costintgraldone in ts

Updated TSFunctionDomainError signature

Instead of getting all stages and the stage index, the function gets
directly the current state (e.g. the one to check).

Added domain error checks at each stage

This patch adds two functions:
1 - TSSetFunctionDomainError
2 - TSFunctionDomainError

The first one to set a user function, the second one to call it.

It also adds the calls to TSFunctionDomainError in all implementations calling TSPostStage.

Fixed issues in the review: fixed TABs; C89 syntax; TSClone comm; error message; clarified implicit equations in docs

update manual and remove confusing comments

adding more comments in the code

ARKIMEX implementation and TSClone notes

added some documetation/fixed some arkimex typos

Cleaned up some issues in TSClone

Replace TSDuplicate with TSClone; all is working but there is still some concern with SNES when the clone is destroyed and a GetSNES and SetSNES is needed

moved everything from W to Z, tested and it works

finalized TSDuplicate implementation and testing

TSErrorWeightedNorm[2|Infinity]: API changes

* Accept two arguments U,Y instead of always using ts->vec_sol
* Accept argument wnormtype intead of use ts->adapt->wnormtype

fix a typo

enable users to evaluate cost integral in the forward run

SNES: Some docs for NASM
TS: Added view for MIMEX
Plex: Silence compiler warnings
Builder: Check for missing numProcs was wrong
PetscFE: Turn off Fortran binding for PetscFECompositeGetMapping()
Plex: Fix big bug in DMPlexGetGlobalFieldOffset_Internal() - If offset is negative (dof is on another proc), then we must have end < start
Builder: Allow override of numProcs
Plex: Fix Fortran wrappers for DMLabelView() and DMPlexDistribute()
Plex+Label: Added Fortran wrapper for DMPlexCreateLabel()
Plex: Dammit, how did this not get checked in?
Plex: Refiner check for hybrid cells must use hybrid faces as well - Ghost cells in FV method are hybrid
TS: MIMEX now uses work vectors for correct grid
Plex: Adding support for FV in automatic interpolator construction - Notice that the injector cannot do the right thing until we scrap VecScatter
Plex+FEM: Using PetscFVGetDualSpace()
SNES+Doc: Added Options Database keys
PetscFV: Added PetscFVRefine() - This allows interpolation to finer grids needed for FAS
PetscFV: Added a dual space for calculating projections
DM: Better error checking in DMCoarsen()
DMDT+PetscFE: Added PetscQuadratureExpandComposite() - Replaces PetscFECompositeExpandQuadrature() - Added PetscFECompositeGetMapping()
Plex: Fixed complex type error
